Abstract
Description
- The field of the invention relates to barrier operator systems and, more specifically, to the barriers used in these systems.
- Different types of moveable barrier operators have been sold over the years and these systems have been used to actuate various types of moveable barriers. For example, garage door operators have been used to move garage doors and gate operators have been used to open and close gates.
- Such barrier movement operators may include various mechanisms to open and close the barrier. For instance, a wall control unit may be coupled to the barrier movement operator and sends signals to a head unit thereby causing the head unit to open and close the barrier. In addition, operators often include a receiver unit at the head unit to receive wireless transmissions from a hand-held code transmitter or from a keypad transmitter, which may be affixed to the outside of the area closed by the barrier or other structure.
- As mentioned, gate operators are one type of barrier operator and are often used to control entry to areas such as parking lots, buildings, garages, and toll roads. Gate operators are typically constructed of a rigid, single-piece extendable arm. The arm, for instance, constructed of a material such as wood or metal, is positioned parallel to the ground to prevent entry to a protected area. On the other hand, when entry is desired, the arm is moved in an arcuate path upward to allow the vehicle or person to pass through the opening into the protected area.
- Unfortunately, the barriers used in these previous systems are bulky and require the presence of an open arc of space to allow the barrier to be placed in the open position. This can be a problem in many circumstances, such as in many enclosed areas, where upward space is at a premium. In addition, as the arm swings downward, the bottom of the barrier arm needs to be protected from impacting an obstruction. For instance, various secondary safety devices (e.g., motion sensors, IR beams) need to be employed to prevent damage from obstructions. These devices can be expensive and bulky, leading to increased system cost and user inconvenience.
- A barrier operator is provided having a telescoping arm. The use of a telescoping arm saves space and does not require an open arc of space above the arm. Since arcuate movement of the arm is not required (i.e., only the tip of the arm moves), only the tip area of the arm need be protected from obstructions. Consequently, simpler and less expensive secondary safety devices can be used to protect the tip and these devices are not needed to protect the rest of the barrier.
- In many of these embodiments, a moveable barrier operator system includes a telescoping barrier arm. A motor is coupled to the telescoping barrier arm for extending the telescoping barrier arm from a retracted position to an extended position and retracting the arm from the extended position to the retracted position. A controller is coupled to the motor for selectively activating the motor to extend and retract the arm.
- A secondary safety device may be included in the system to prevent the telescoping barrier arm from contacting an object in a pathway of the telescoping barrier arm. In one example, the secondary safety device may be positioned to protect the tip of the arm from impacts with obstructions.
- Other devices may also be used in conjunction with the telescoping barrier arm in the system. For example, a detector for detecting a power outage may be used. In one example, the controller may be programmed to actuate the motor upon detection of a power outage and the barrier arm may be retracted, held in a current position, or extended. In another example, a manual override mechanism may be provided to manually override actions of the controller.
- The system may be operated according to various modes of operation. For example, the controller may operate the telescoping barrier arm in a failsafe mode that allows a user to escape the telescoping barrier arm upon detection of a predetermined condition, such as a collision with the user. In another example, the controller may operate the telescoping barrier arm in a fail-secure mode that excludes users from entering a secure area protected by the operator upon detection of a predetermined condition such as the detection of an unauthorized attempt to gain entry to the secure area.
- Various types of mechanisms can be used to extend the telescoping barrier arm from a closed position to an open position. For instance, the motor may drive the telescoping barrier arm into its extended position using springs.
- Thus, a barrier operator having a telescoping arm is provided. The telescoping arm saves space and does not require an open arc of space above the arm. Since arcuate movement of the arm is not required, only the tip area of the arm need be protected from collisions with obstructions, and, consequently, simpler and inexpensive secondary safety devices can be used in the system.

FIG. 1 a, one example of a barrier operator system using a telescoping barrier arm is described. A moveable barrier operator system includes achassis 100. Thechassis 100 houses a controller, a motor, and a mechanism for extending and retracting atelescoping barrier arm 102. Alternatively, the mechanism for extending and retracting the arm may be positioned outside of thechassis 100. - The
barrier arm 102 includes afirst member 104, asecond member 106, and athird member 108. This is one example only and it will be appreciated that the barrier arm may include any number of members. Each of themembers first member 104 is less than the width of thesecond member 106. The width of thesecond member 106 is less than the width of thethird member 108. Consequently, in this example, when in the retracted position, the first member is housed within thesecond member 106. Together, the first andsecond members third members chassis 100. - The barrier operator system may be actuated in a number of different ways. For example, a
transmitter 112 may be used to send a signal to anantenna 110 to the barrier operator system. Once received, the signal may cause thebarrier 102 to be extended or retracted. In another example, a user or vehicle may be enter amagnetic sensing loop 114, which causes a signal to be sent to the barrier operator system. This, in turn, may cause the barrier arm to be extended or retracted. Other examples of actuators are possible. - Other devices may also be used in conjunction with the moveable barrier operator system. For example, a detector for detecting a power outage may be positioned within the
chassis 100. In one example, the barrier operator may be actuated upon detection of a power outage and thebarrier arm 102 may be retracted, held in a current position, or extended. - A manual override mechanism may also be provided in the system to manually override actions of the system. For example, a
manual override button 118 may be provided to allow a user to manually override the actions of the controller. - The system may additionally be operated according to various modes of operation. For example, the operator may operate the telescoping barrier arm in a failsafe mode that allows a user to escape the
telescoping barrier arm 102 upon detection of a predetermined condition such as a collision with the user or object. In another example, the operator may operate thetelescoping barrier arm 102 in a fail-secure mode that excludes users from entering a secure area protected by thearm 102 upon detection of a predetermined condition such as the detection of an unauthorized attempt to gain entry into the secure area. - The
barrier arm 102 may have adetector 116 that detects the presence of objects in the path of thearm 102 as thearm 102 extends. In one approach, the sensor is positioned on the tip of thefirst member 104. Alternatively, the detector may be positioned in other locations such as above or below any of themembers - Referring now to
FIG. 1 b, an example of the barrier system ofFIG. 1 with the telescoping barrier arm in the retracted position is described. In this example, themembers chassis 100. Alternatively, at least a small length of these members may extend slightly outside thechassis 100. In still another example, themembers chassis 100 when retracted. In this case, themembers - Referring now to
FIG. 2 , one example of a moveable barrier system using a telescoping barrier arm is described. A moveablebarrier operator chassis 200 includes atelescoping barrier arm 202, which is coupled to amotor 212 via a motor/arm interface 210. Acontroller 214 is coupled to and controls the operation of themotor 212. - The
controller 214 is also coupled to asensor interface 216 and anRF interface 218. Thesensor interface 216 receives signals from an obstruction detection sensor 224 (at the tip of the telescoping barrier arm 202) via awire 226. Thesensor interface 216 also receives signals from anexternal presence sensor 220. - The
controller 214 additionally receives signals from amanual override indicator 228. Themanual override indicator 228 may be a button or switch that allows a user to override the actions of thecontroller 214. - The
RF interface 218 receives signals from atransmitter 222. These signals can be used to actuate thebarrier arm 202. - The
motor 212 and other components of the system are connected to apower supply 234 via apower line 232. Adetector 230 determines whether a power outage has occurred (i.e., power from thepower supply 234 is no longer detected). - The
telescoping barrier arm 202 includes afirst member 204, asecond member 206, and athird member 208. Asensor 224 is positioned at the tip of thefirst member 204. Thesensor 224 can be contained within theoperator 200 in such a way that it can still sense an obstruction at the tip of the barrier. In the extended position, thesecond member 206 extends from thethird member 208 and thefirst member 204 extends from thesecond member 206. It will be appreciated that any number of members can be used. It will also be understood that various mechanisms such as springs (not shown) can be used between themembers motor 212 andmotor arm interface 210 to end and retract thetelescoping arm 202. - The
motor arm interface 212 includes one or more circuits and/or mechanisms that allow the motor to extend and retract thetelescoping arm 202. In this regard, the motor arm interface may include springs, gears, pulleys or any other type of mechanism or circuit that allow the motor to drive the telescoping arm from a retracted position to an extended position and vice versa. - The
sensor interface 216 converts signals received from thesensor 224 and theexternal sensor 220 into a format useable by thecontroller 214. Similarly, theRF interface 218 converts signals received from thetransmitter 222 into a format usable by thecontroller 214. - In one example of the operation of the system of
FIG. 2 , themotor 212 is activated to move thetelescoping barrier arm 202 from a retracted position to an extended position and retract the arm from the extended position to the retracted position. - The
sensor 224 provides a secondary safety device to protect thetelescoping barrier arm 202 from contacting an object in the pathway of thetelescoping barrier arm 202. As shown, thesensor 224 may be positioned to protect the tip of thearm 202 from impacts with obstructions. - As mentioned, the
detector 230 may be used to detect whether a power outage has occurred and communicates this information to thecontroller 214. In one example, thecontroller 214 may be programmed to actuate the motor upon detection of a power outage and thebarrier arm 202 may be retracted, held in a current position, or extended. In another example, a manual override mechanism (e.g., indicator 228) may allow for the manual override actions of thecontroller 214. - The system may be operated according to various modes of operation. For example, the
controller 214 may operate thetelescoping barrier arm 202 in a failsafe mode that allows a user to escape thetelescoping barrier arm 202 upon detection of a predetermined condition such as a collision with the user. In another example, thecontroller 214 may operate thetelescoping barrier arm 202 in a fail-secure mode that excludes users from entering a secure area protected by the operator upon detection of a predetermined condition such as the detection of an unauthorized attempt to gain entry to the secure area. The system may be operated in other modes as well. - Referring now to
FIG. 3 a, a cross sectional view of a telescoping barrier arm in the extended position is described. Atelescoping arm 300 includes afirst member 302,second member 304, andthird member 306. Themember 304 extends outward from themember 306 and themember 302 extends outward from themember 304. Each of themembers first member 302 is less than the width of thesecond member 304. The width of thesecond member 304 is less than the width of thethird member 306. Themembers - A
sensor 312 is provided at the tip of themember 302. Thesensor 312 detects the presence of objects in the path of thearm 300 as thearm 300 extends. Thesensor 312 may be a photobeam detector (retro-reflective object detecting), proximity detector (e.g., a capacitive sensor), or a pressure detector to give some examples. - A
spring 308 is used to push themember 302 outward of themember 304. Aspring 310 is used to push themember 304 outward from themember 306. A motor and other mechanical components (not shown) can be used as is known in the art to move the springs and extend and retract themembers - Referring now to
FIG. 3 b,a cross sectional view of a telescoping barrier arm in the retracted position is described. As shown, thefirst member 302 has been retracted into thesecond member 304 and the first andsecond members third member 306. Thesprings - Referring now to
FIGS. 4 a and 4 b, another example of a barrier system using a telescoping barrier arm is described. A moveable barrier operator system includes achassis 400. Thechassis 400 houses a controller, a motor, and a mechanism for extending and retracting atelescoping barrier arm 401. In this example, thebarrier arm 401 includes afirst member 410, asecond member 408, athird member 406, afourth member 404, and afifth member 402. A supportingmember 412 provides support and strength to hold themembers - Each of the
members first member 402 is greater than the width of thesecond member 404. The width of thesecond member 404 is greater than the width of thethird member 406. The width of thethird member 406 is greater than the width of thethird member 408. Finally, the width of thesecond member 408 is greater than the width of thethird member 410. - In this example and now referring to
FIG. 4 b, when in the retracted position, thefirst member 410 is housed within thesecond member 408. Together, the first andsecond members third member 406. The first, second andthird members fourth member 404. Finally, when fully retracted, the first, second, third, andfourth members fifth member 402. In this example, the retracted members remain on the outside of thechassis 400. As mentioned, the supportingmember 412 provides support and strength to hold themembers - Thus, a barrier operator having a telescoping arm is provided. The telescoping arm saves space and does not require an open arc of space above the arm in order to open. Since arcuate movement of the arm is not needed, only the tip portion of the arm need be protected from obstructions, resulting in a simpler and less expensive system.
- While there has been illustrated and described particular embodiments of the present invention, it will be appreciated that numerous changes and modifications will occur to those skilled in the art, and it is intended in the appended claims to cover all those changes and modifications which fall within the true scope of the present invention.
